PATENT i FRANKLIN D. FORNEY, OF GLENVILLE, PENNSYLVANIA, ASSIGNOR OFONE-HALF TO J. A. SHUE, OF SAME PLACE.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 575,030, dated January12, 1897.

Application filed June l0, 1896. Serial No. 594,976. (No model.)

To all whom, t may concern:

Be it known that I, FRANKLIN D. FORNEY, a citizen of the United States,residing at Glenville, in the county of York and State of Pennsylvania,have invented a new and useful Lubricator, of which the following is aspecification.

My invention relates to a lubricating device, and has for its object toprovide a simple and efficient construction and arrangement of partswhereby the oil is fed only when required and is kept at a uniform depthin the reservoir provided for its reception to avoid flooding, and,furthermore, to provide means for conveying back to the reservoir thewaste lubricant to prevent the saine from working out beyond thebearings.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a lubricating deviceconstructed in accordance with my invention. Fig. 2 is a longitudinalsection of the same. Fig. 3 -is a transverse section taken in the planeof the axis of the shaft. Fig. 4 is a horizontal sec- Fig. 5 is atransverse section of a slightly-modified arrangement of the lubricatingdevice adapted for use in connection with car-axles.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The body portion or shell 1 of the lubricator is provided with areservoir or well 2, from the bottom of which extends a channel 3 to abasin or cavity 4, in which is arranged a feeding-disk 5, fixed to theshaft (5, said feeding-disk being tapered toward its periphery and beingadapted to dip into the lubrieating material in the basin, which issupplied from the reservoir. The basin or cavity in which the disk isarranged is constructed to iit the latter snugly to prevent the diskfrom carrying an excessive amountof lubricant.

The bearings 7, which are arranged upon opposite sides of the basin orcavity, are cut away to form the waste-receptacles 8, closed at theirouter sides by guards 9, whereby lthe oil or other lubricant which iscarried by the shaft beyond the'bearings is received by thewaste-receptacles, which connect by means of passages lO, havingdownwardly-inclined floors, with the well or reservoir 2 to prevent theescape of the lubricant beyond the shell.

Projecting through the top of the shell and dipping into the contents ofthe well or res ervoir is the feed-tube 1l of an oil-cup 12, which formsa tank to contain a quantity of lubricant to be fed to the well orreservoir. This oil-cup is provided with a screw-cap 13, having suitablepacking 14 to form an airtight joint, and the feed-tube is provided witha controlling-cock 15, which should be closed during the filling of thecup to prevent an excessive amount of oil from entering the well orreservoir. After the cap of the oilcup has been replaced thecont-rolling-cock 15 may be opened to allow lubricant to feed to thewell or reservoir, and when the lubricant has filled the well orreservoir sufficiently to cause the lower extremity of the feed-tube todip thereinto the flow will cease. As the oil becomes used and thesurface thereof falls below the plane of the lower extremity of thefeed-tube an additional supply will be fed to the well or reservoir fromthe oil-cup.

From the above description it will be seen that the device is simple andthat lubricating material which passes beyond the bearings of the shaftis caught by the waste-receptacles and returned to the Well orreservoir, while the arrangement of the feedingdisk upon the shaftbetween the bearings of the latter serves to maintain the bearingsthoroughly lubricated.

Then the device is used in connection with car-axles, a single oil-cup,as shown at 16, is preferably used to Afeed oil through branchfeed-pipes 17 to two reservoirs, the construe tion of the interiors ofthe shells 18 being identical with that above described.

The reservoir is preferably provided with an air-inlet port l0 toprovide for the proper liowing of the lubricant t0 the feeding-disk, andover said port is arranged a shield or guard 2O to prevent dust fromaccumulating therein.

Various changes in the form, proportion,

IOCv

and the minor details of construction may be resorted to Withoutdeparting from the spirit or sacrificing any of the advantages of thisinvention.

Having described my invention, what I claim is- 1. A lubricator forshafts having a basin or cavity, means for maintaining lubricatingmaterial at a uniform depth in said basin or cavity, and alubricating-disk carried by the shaft and tapered toward its peripheryto dip into the lubricant contained in the basirnon cavity, the Walls ofthe basin or cavity fitting snugly against the surfaces of said disk,substantially as specified.

2. A lubricator for shafts having spaced bearings, an interposed basinor cavity, a Well or reservoir and means for maintaining lubricatingmaterial ata uniform depth therein, said Well or reservoir being incommunication with the basin or cavity, a lubricatingdisk arranged inthe basin or cavity and adapted to be carried by a shaft, andwastereceptacles arranged contiguous to and beyond the bearings andcommunicating by declined passages with the well or reservoir,substantially as specified.

A lubricator having a Well or reservoir, a basin or cavity incommunication with the Well or reservoir and arranged contiguous to ashaft-bearing to receive a lubricating-disk carried by the shaft, and anair-tight oil-cup having a feed-tube extending into the Well orreservoir and adapted to dip into the contents thereof to regulate theflow of lubricant, substantially as specified.

4E. A lubricator having a Well or reservoir, a basin or cavity arrangedcontiguous to a shaft-bearing and adapted to receive a lubrieating-diskcarried by the shaft, an air-tight oil-cup having a removable cap, and afeedtube provided With a controlling-top and extending from the oil-cupto the Well or reservoir, the extremity of said feed-tube dipping intothe contents of the Well or reservoir to maintain a uniform depth oflubricant therein, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
